Question

1) A container with 2 5⁄6gallons of weed killer can spray 3 5⁄6lawns.How many gallons would it take to spray 3 lawns?

2)It takes 3 2⁄6spoons of chocolate syrup to make 2 3⁄5gallons ofchocolate milk. How many spoons of syrup would it take to make 4gallons of chocolate milk?

Answer 1

1. 2 5/23 gallons

2. 5 5/39 spoons of syrup

Explanation:

1. A container with 17/6 gallons of weed killer can spray 23/6 lawns. We need to figure out how much weed killer it would take to spray 3 lawns. Divide 17/6 by 23/6.

17/6 / 23/6

17/6 * 6/23

The two 6's cancel out.

17/23 * 3/1

51/23

It would take 2 5/23 gallons to spray 3 lawns.

2. It takes 20/6 spoons of chocolate syrup to make 13/5 gallons of chocolate mink. We need to know how many spoons of syrup it would take to make 4 gallons of chocolate milk.

20/6 / 13/5

20/6 * 5/13

10/3 * 5/13

50/39

(50 * 4)/39

200/39

It would take 5 5/39 spoons of syrup to make 4 gallons of chocolate milk.

Answer 2

51/23 or 2 5/23

Explanation:

2 5/6= 17/6

3 5/6= 23/6

17/6÷23/6

17/6×6/23=

17/23=1 lawn

17/23×3=51/23

A container with gallons of weed killer can spray = lawans

∵ in lawn the week killer can spray = gallons

∴ in 1 lawn the weed killer is used = × gallon

∴ in 3 lawns the weed killer can spray = × × 3 = gallon = gallons
